The specific embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but embodiment of the present utility model is not limited to this.
Consult shown in Fig. 1-Fig. 5, the utility model provides a kind of bolt-type machine-roomless lift inspection platform anti-mobile device, comprise a pair of latch that is fixed on car upper beam 1, be fixed on a pair of plug housing 10 coordinating on guide rail 9 and with latch, and be installed on the UKS switch 8 on latch, and there is locking state between latch and plug housing 10, mobile status and reset mode, this anti-mobile device also comprises a flexible restoring organ for latch and plug housing 10 are resetted to reset mode from locking state or mobile status, an and catch gear for latch and plug housing 10 are maintained the lock status, UKS switch 8 is manual reset switch, and when latch and plug housing 10 maintains the lock status or during mobile status, UKS switch 8 is in triggering state.
Wherein, and between latch and plug housing 10, having locking state, mobile status and reset mode is also definition of the prior art, be that locking state is pin hole 15 lockings of latch and plug housing 10, mobile status is latch with respect to the pin hole 15 of plug housing 10 in mobile status, and reset mode is the state of latch in starting most.
Concrete, on the outer face of U-shaped base 6, be also provided with for the UKS switch mounting hole 13 of UKS switch 8 is installed, and this UKS switch mounting hole 13 is positioned at the lower end of the first circular hole 11.
Concrete, described latch comprises the U-shaped base 6 being installed on car upper beam 1, be located at the first circular hole 11 and second circular hole 12 of U-shaped base 6 outer faces and inner end surface, be installed in the first circular hole 11 and the second circular hole 12 movably bearing pin 4, and the movement of this bearing pin 4 makes latch and plug housing 10 in locking state, mobile status or reset mode.
In the present embodiment, described flexible restoring organ comprises snap ring 5 and the elastomeric element 7 that is sheathed on bearing pin 4 and is positioned at U-shaped base 6 inner sides, and described snap ring 5 is between elastomeric element 7 and the inwall of U-shaped base 6; General, elastomeric element 7 is selected spring.
In the present embodiment, described catch gear comprises the short pin 3 of being located at bearing pin 4 rear ends, and the waist hole 14 on the second circular hole 12, and the length of this short pin 3 is less than the length in waist hole 14; When between latch and plug housing 10 during in locking state, when bearing pin 4 inserts pin hole 15, short pin 3 is through waist hole 14, and then rotary pin shaft 4 makes short pin 3 not corresponding with waist hole 14, latch and plug housing 10 can be remained on to locking state.
And for the ease of rotary pin shaft 4, on the bearing pin 4 that is positioned at short pin 3 outsides, be also provided with one and have strong market potential 2, and this length of 2 of having strong market potential is greater than the length of short pin 3, while specifically using, service personnel can be had strong market potential and 2 be made short pin 3 not corresponding with waist hole 14 by rotation.
Above-mentioned short pin 3 and have strong market potential and 2 specifically can be provided with in the rear end of bearing pin 4 two through holes, and by short pin 3 with have strong market potential 2 through these two through holes, then be welded and fixed.
The front end of described bearing pin 4 is half cone, can, so that bearing pin 4 is more easily installed, and more easily coordinate with pin hole 15.
Because the quantity of latch and plug housing 10 is two (a pair of), can prevent that car from twisting.
1-Fig. 5 is described further principle of work of the present utility model by reference to the accompanying drawings more below: latch and plug housing 10 hold reset states when elevator normally moves, when machine-roomless lift is overhauled, the bearing pin of the latch on car upper beam 14 is released, insert in the pin hole 15 of plug housing 10 on guide rail 9, make short pin 3 through waist hole 14, then rotation has strong market potential 2, be that latch and plug housing 10 maintain the lock status, the relative car guide rail of elevator is fixed, when releasing, triggers the bearing pin 4 of latch UKS switch motion, disconnect the safety return circuit of elevator, force the elevator can only inspection travel, allow staff have a pulsation-free service platform, guaranteed operation safety.After service personnel work is complete, rotation is had strong market potential and 2 is made short pin 3 exit waist hole 14, at elastomeric element 7(, be spring) effect under, bearing pin 4 resets, and in the time of bearing pin 4 must being retracted into original reset mode, ability reset UKS switch 8, now elevator could normally move, otherwise elevator is in maintenance or disconnection safety return circuit state.
Elastomeric element 7(in the utility model is spring) can prevent that the force of inertia that the normal acceleration-deceleration in service of elevator produces from can make latch produce misoperation, the spring energy that this spring produces is offset force of inertia makes bearing pin 4 not produce misoperation, avoids damaging other hoistway parts.And UKS switch 8 is set for manual reset switch, it can not automatically reset after can making latch trigger UKS switch, can guarantee that under the non-reset mode of latch, manual reset switch remains on triggering state always simultaneously, even if hand-reset is also infeasible, guaranteed greatly safety.
Above-described embodiment is preferably embodiment of the utility model; but embodiment of the present utility model is not restricted to the described embodiments; other any do not deviate from change, the modification done under Spirit Essence of the present utility model and principle, substitutes, combination, simplify; all should be equivalent substitute mode, within being included in protection domain of the present utility model.
